subject: Advantages Of Free To Air Receivers [print this page] Although at an early stage of television some should bear the cost of upgrades, eventually broadcasting programs using digital technology and free to air (fta) is less expensive because, among other things, it allows more efficient use of power emission transmitters. However, the reception of digital television will involve costs for the citizens, as is the purchase of a decoder or an integrated TV.
Ability to provide interactive services
Interactivity refers to the user's ability to influence the programs that will receive or the services to which you are accessing. In the case of advertising, for example, users can access information on the products or services advertised to be of interest to them, and may even proceed to purchase online using your phone or Internet connection. The programs may be, for example, voting in a contest or bet on who will win a game, or choose the end of a fictional series, enter the time of their region, and so on.
Why decide on a digital TV and FTA standard?
Without doubt, decide for a technology standard is unprecedented in telecommunications policy, by contrast, have always defended the technological neutrality, leaving the job market "decide" what is the best alternative or standard for a particular service. But this time, we're talking about transforming our free broadcast TV reception, present in all households in the country in a better quality service at the lowest possible price for everybody.
The analog television system used worldwide mostly, called NTSC (National Television System Committee) also used in the U.S., Japan and many other countries, was chosen in our case in the late '70s. Because this standard was compatible with the old black and white televisions, it was necessary to make a very complex transition, as someone who bought a color TV was in color while the old black and white continued to operate normally. The selection of standard at the time, rather than strictly technical considerations, sought the option to have more market projections in the future and allow teams to get cheaper, rejecting any temptation to define a proper standard.
By contrast, today the problem of digitalization of terrestrial television (TV open signal), in contrast to the change in black and white to color, lies in the current analog television receivers are incompatible with this new technology, what users will necessarily have to buy digital TVs or add a decoder to your existing televisions.
Furthermore, the digitization of digital television is operating worldwide with three standards: ATSC (Advanced Television Systems Committee) come from the U.S., DVB (Digital Video Broadcasting) of the European Community and ISDB (Integrated Services Digital Broadcasting) of Japanese origin .
Also, among these digital TV standards is inconsistent operation. In practice, this means that if we broadcast television is received by all, both the television and viewers should enjoy the same digital television standard in both the transmission and reception.
